R14

 

The thermodynamic properties of refrigerant R14 are provided by Martin-Hou equation of state (A.I.Ch.E. Journal, 1:142, 1955).  Fitted parameters are from Downing and Knight, DuPont Technical Bulletin RT-52, 1971.

 

The reference state is determined by setting specific enthalpy to 142.5 kJ/kg and specific entropy to 1.784 kJ/kg-K for saturated liquid at -100 C.

 

Transport properties are provided using correlations given in:

Yaws, Carl L., ed. Chemical Properties Handbook. New York: McGraw-Hill, 1999 data are from Yaws,

 

Range of applicability for transport function correlations:

Gas-phase viscosity: 145 K to 900 K

Liquid-phase viscosity: 90 K to 227.5 K

Gas-phase thermal conductivity: 145 K to 750K

Liquid-phase thermal conductivity: 90 K to 220 K

 

Surface tension data are provided using the information in:
